Diversitronics ELS-44 (0411) Matrix Lighting Controller

Great chase control unit from Diversitronics.  This is the ELS-44 (Entertainment Lighting System) controller.  The unit functions as a 4 channel color organ with optional matrix output.  The unit connects to matched Diversitronics RSU Series power packs via 0 - 10 volt analogue output through 1/4" connections then on to lighting units.  A cool feature of this unit is auto 'Bump' buttons for manual control with matched LED meters.  Most units from this generation lacked these features.  Very rare and built like a tank!  Great unit made in the US.
